To Next PageTo Next PageWhat to do if my Sharp VL-AH30U has no picture?
If your Sharp Camcorder shows no picture, examine IC551 (Lens driver) and its peripherals. Also, inspect IC706 (camera CPU part of I chip µ-computer), IC551 (Lens driver), and their surrounding components.
Why is my Sharp Camcorder not video recording?
If your Sharp Camcorder isn't recording video, check the Y/C circuit and the head amplifier circuit.
How to troubleshoot a Sharp VL-AH30U with no function at all?
If your Sharp Camcorder is completely unresponsive, check the power circuit and the system control circuit. Also, check the system control and loading motor circuit.
What to do if the output voltage of Q2901, 1pin is not more than 7V in Sharp VL-AH30U Camcorder?
If the output voltage of Q2901, 1pin is not more than 7V in your Sharp Camcorder, check the AC adapter.
What to do if Q2905 collect voltage is not indicating in Sharp VL-AH30U?
If Q2905 collect voltage is not indicating in your Sharp Camcorder, check Q2905, IC2901, and the surrounding circuits.
What to do if start "H" Is ADP-DET "H" in Sharp Camcorder?
If the "H" Is ADP-DET "H" in your Sharp Camcorder, check the circuit of SYSCON.
What to do if BAT DET is "OV" in Sharp VL-AH30U Camcorder?
If BAT DET is "OV" in your Sharp Camcorder, check Q2911, R2914, R2915, and the battery terminal unit.
What to do if CHG-ON is "L" or "H" in Sharp Camcorder?
If CHG-ON is "L" or "H" in your Sharp Camcorder, check the circuit of SYSCON.
